THNX GETMOA :),
F1, bhai its 2005, not ur 1960s
DOHC means (Dual Over Head Cam) not (Dual over cam of yours)
u think making a DOHC engine costs the same like an engine of F1? yes corolla 1.3 XLI, GLI, Se Saloon all have DOHC, and even civic has 4 vavles, baleno has 4 valves, every 1.3 or 1.6 cars have 4 vavles!!!
every car now being produced is either DOHC or has Variable intake system!
secondly, sali2002, so u mean to say tht if the road is long, for example 5 kms and u race a diesel, so due to long length of road, the power of diesel will increase??? wht kind of explanation is this, plz mind explaining this to us. WHERE AS I THINK THT, AT ONLY HIGH SPEEDS, DIESELS OUT PERFORM PETROL DUE TO MORE POWER AGAINST DRAG! TRY DRIVING A 2.0D, AND FEEL THE SLAGGISH PICK IN INITIAL GEARS UPTO 120. THEN FEEL THE TORQUE OR POWER IN 4TH AND 5TH GEAR WITH 5 PPL IN UR CAR, AND WITH 5 PPL IN GLI, RACING BESIDE U
